[edit] Standard sizes

Width by length. Metric sizes (Europe) rounded to nearest half decimetre; inch sizes (U.S., UK, Australia) rounded to nearest inch.

Single, Twin	39 in × 75 in	36 in × 75 in	36 in × 75 in	36 in × 79 in
Single, Twin	1 m × 1.9 m	0.9 m × 1.9 m	0.9 m × 1.9 m	0.9 m × 2 m

Double, Full	1.35 m × 1.9 m	1.35 m × 1.9 m	1.35 m × 1.9 m	1.4 m × 2 m
Queen	60 in × 80 in	60 in × 80 in	60 in × 80 in	63 in × 79 in
Queen	1.5 m × 2.05 m	1.5 m × 2 m	1.5 m × 2.05 m	1.6 m × 2 m
King, (Super King)	76 in × 80 in	72 in × 78 in	72 in × 80 in	71 in × 79 in
King, (Super King)	1.95 m × 2.05 m	1.85 m × 2 m	1.85 m × 2.05 m	1.8 m × 2 m

The sizes in the UK, other than the Double, vary compared to the U.S. sizes, being generally smaller. The U.S. Queen corresponds to UK King and King to Super King. The European or continental basic sizes are similar to the UK but have a set length of 2 metres.

These dimensions are for the mattress—the actual bed frame will be a little bigger in order to fully encompass and support the mattress. The thickness of the mattress may vary considerably.
